The Lowdown
Alright, this is Rusty, and I gotta be straight with you – this one's a tough pill to swallow. Looking at the whole 16-day window for Kohala Lighthouse, it's a real bummer. There’s no good surf on the horizon, not a single day where the stars align. The setup is a classic case of the tradewinds ruining the party.
The trouble starts Friday, August 7th, and it just doesn't let up. We’ve got a moderate amount of swell energy building, but it’s coming from the ENE. The problem is that the wind is whipping from the same direction, at 19 mph, straight cross-shore. That’s a recipe for lumpy, choppy, messy conditions right from the get-go. The swell is a short, weak 4 ft with a period of only 4 seconds and combined energy of just 65 – that’s barely a ripple, and it's a messy one.
The swell does build through the first week, hitting 7 ft to 7 ft by the weekend of the 15th and 16th, with the combined energy climbing into the moderate range (over 600). But the wind just gets stronger, with gusts up to 25 mph, creating a strong cross-shore chop. It's the kind of energy that would be exciting if the wind would just cooperate, but it won't. The period stays short, around 8 seconds, so it's all wind-swell, not any real groundswell.
After that, the swell tapers off into the second week, but the wind never lets up, just shifting to a cross-onshore direction. The water temp is about average for the time of year, but you won't be in the water long enough to notice.
Basically, for the entire 16-day run, from August 7th right through to August 22nd, every single session is rated as poor. The reef is exposed, but the wind is constantly trashing it. For a spot like this, with that persistent cross-shore wind, it's honestly more interesting for kite surfing than paddle surfing. There's just no clean face to be found.
I hate to say it, but there's nothing to recommend. Sometimes the forecast is just a long, blank stretch. This is one of those times. Keep the board in the car, but maybe don't take it out of the bag. We'll see what the next model run brings.

Information about the Kohala Lighthouse Surf forecast
The above surf forecast table for Kohala Lighthouse provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kohala Lighthouse can be found by selecting the local surf guide option on the grey menu. Our Kohala Lighthouse surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kohala Lighthouse) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kohala Lighthouse may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
